This isn't the first time McDonald's has dyed its burger buns, and it won't be the last, but it's always slightly unnerving.

The burger typically makes a yearly comeback during the Spring and features a teriyaki patty with an egg on top and pink mayo Japanese radish spread. But this year, McDonald's added an extra twist — burger buns with a light pink hue.
